COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes
The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Read More
Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)
This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... Read More
Analysis of D-Shaped Toroidal Superconductive Coils for Medium Size Fusion Experiment Facility
The research in magnetic confinement fusion is carried out through electromagnetic machines, with a toroidal geometry, where a hot plasma of heavy hydrogen isotopes (deuterium and tritium) is contained in a vacuum vessel. Due to the very high temperatures reached by the plasma, strong ... Read More
Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting
Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Read More
Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes
Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Read More
Simulator for the Development of Electromagnetic Heart Assist Devices
Every year, in the United States alone, more than 40,000 infants are born with congenital heart defects (CHD) and an additional 550,000 adults are diagnosed with heart failure. Every year, $110 billion is spent on treating heart attacks and $20-39 billion on heart failure in the US. The ... Read More
Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes
Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Read More
Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization
As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Read More
